My take on that would be to introduce read-only pages and a context index (tree or hashtable) in Xen, and then handle the CoW part in the guest OSes. That removes the need for any policy on how to handle overcommits in Xen or Dom0, in the case where all domUs decide to fill up their pages with random data.
